the rear drive shaft fell outta my truck yesterday, the universal joint shattered. fixed that. now im thinking my gears are hooped too...

In park the truck will roll foward or backwards. the drive shaft just spins when its in D or R. when i put it back in park ( i beleive its the fly wheel?) somthing makes a weird, dont know how to explain it noise, not really grinding but spinning, pretty sure its the fly wheel. I have the old school guages, the bar kind (88-92 or somthing?) when its in reverse the spedomerter sits at 20km/h, which is revs right?

im lost, none of my buddies know, next thing i gotta do it take it to the shop any advice asap would be aaaaawesome

Sorry man, your rear end has grenaded.

Either:
1. Oinion gear broke
2. Ring gear broke
3. Spider gears broke

Or some combination of all three. I have had this ahhpen a few times to me. Its a bad feeling seing that drivehsfat spin while the truck sits still.

Pull the rear cover and see what carnage is inside.

You will need to get someone to rebuild your rear end.

if you ever wanted to do a rear gear swap, now might be the time to do so.

EDIT Nevermid about the ratio change, I just realized you have a 4x4. If you change ratios, you ahve to do both teh front AND rear gears, unless you NEVER use 4wd EVER.

At least you can drive it to the shop. Just throw it in 4wd and away you go.

Goodluck
peace

4x4 doesnt work either....in 4hi, 4lo, doesnt work at all, when i throw it in reverse it sounds like it clunks into gear, but it doesnt move.:bash: :help:

I did the same thing in my truck here a few years back. It happened when i was running along at about 75-80. Cept, when i did it, the DS didnt fall out until i got stopped. The vibrations took out the tranny, pissed me off, it was a fairly fresh tranny too....

you can get a 3.73 but you have to regear the front too...twice the money

Sorry about the rear end. i recommend upgrading it. No reason to rebuild a weak unit. Look around for a 2500 6 lug truck and use that rear differential It is a semi flaoting 14. Real soldi rear diff unless you go more than a 36 inch tire.

If it wont move in 4wd then your transfer case or tranny is fubared also.

for 33's i'd go to 3.73 for the best results, but your 3.42 gears should be just fine. ive heard on here a good estimate is 600 for both axles, but i'm not sure. if you lived closer i'd help you with the rear axle gearing.

alright. its in the shop, they say its the tranny. a wrecker wants 900$ cnd for a used TH700. does that sound alright? or should i be able to find one cheaper then that:banghead: i also need a rear end:whyme:

I wouldn't spend $900 on a used trans, just get yours rebuilt.

Savier

just over 1000$ to get it rebuilt

A little over 1000 for fresh new parts VS 900 for a used dont know what its been through before you got it tranny? I think Id drop the cash and get the new parts rather than getting a used tranny that someone SAYS is good, You might be back in the shop sooner then youd like.
